The simulation runs as a netbeans project and is all cli (no graphics)... Shouldn't be too hard to make it a standalone graphics thing. I don't have a standalone server that I can put it up and host it as a servlet - that would be ideal, then folks can just plug in the code, adjust some parameters, and off it goes.

I am definitely interested in helping on the widget in any way that I can.

A suggestion for the first SWAP activity in 3.3. The initial example does not say where the left hand should be at the start of the short SWAP program. I would add a line right at the start that says "Move LH to position 0". JR

1 Jump to Line 3 if LH lt RH2 SWAP3 Jump to Line 6 if RHPos is 74 Shift RH to R5 Jump to Line 16 Move LH to Position 67 Jump to Line 9 if LH lt RH8 SWAP9 Jump to Line 12 if LHPos is 010 Shift LH to L12 STOP

I am new to the teacher community, I was introduced by a friend of mine, I usually just follow the instructions with my students and we find the answers along the way. But we seem to have a discrepancy on the homework I assigned (the Optional Challenges), and if it's not of any problem, could someone please direct me to the answers for the assignment. Please and Thankyou.

Welp. Guilty. I didn't put solutions to all the problems because I didn't have time, I just thought they were interesting problems. Happy to hash out solutions here on the forum though if someone wants to start.
